HEATING SYSTEM.

SPECIFICATION forming part of Letters Patent No. 755,176, dated March 22, 1904.

Application filed April 25, 1902.'

To all whom it may concern:

Be it known that I, JAMEs M. SEYMOUR, Jr. a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Heating Systems; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to, figures of reference marked thereon, which form a part of this specification.

The present invention has reference generally to improvements in heating systems in which steam or other similar heating medium is caused to flow to radiators or heaters through a suitable system of pipes and there to give off heat, the result of which is that a portion of the heat medium is condensed in the radiators or heaters, forming water, and the radiators or heaters at the same time collecting air as well as foul gases.

The principal object of this invention is to provide a heating system in which the movement of the heating medium is facilitated and, furthermore, in which all the air and foul gases that may collect in the radiators and other heating apparatus are readily removed in a most eflicient and reliable as well as an economical manner; j Y

My present invention therefore consists, primarily, in the improved heating equipment, which comprises a heated stand-pipe through which the air or gases from the radiator or other heater are passed and allowed to escape into the atmosphere at apoint above the building.

I am aware that several devices have been patented foraocomplishing. the results of removing the air or gases from the radiators. One system is to place a condenser at the end of the air-line, another is to place a pump suitable for pumping the air on the end of the air-line and exhausting the air from the system, another is to carry the air-lines back to the return-pipes and pump on the returnpipes, and still another is to carry the air-line into a return-tank from which the air is be- 5 ing pumped continuously. All of these'sys- Serial No. 104,587. (No model.)

tems have their defects and are in operation expensive and liable to get out of order.

To overcome the objections found at present in heating systems provided with means for removing the air and foul gases from the radiators or heaters, I have provided the novel arrangements and combinations of the devices to be presently described and then finally embodied in the clauses of the claim, which are appended to and form a part of the present specification.

My invention is clearly illustrated in the accompanying drawings, in which Figure l is a sectional representation of a building and a smoke-stack, partly in elevation and partly in section, illustrating in connection therewith a steam-heating system in the building and a rising-line or stand-pipe for drawing ofl the air or gases from the radiators arranged directly in the available smoke-stack. Fig. 2 is a sectional representation of an ordinary dwelling-house provided with a flue leading from the basement to a point above the roof and illustrating in con- .nection with the building and flue a steamheating system and the rising-line leading directly from the basement into the said flue to the roof of the building Fig. 3 is a sectional representation of a building and a smokestack, partly in elevation and partly in section, illustrating in connection therewith a steam-heating system comprising a plurality of air lines terminating in a common header and a rising-line or stand-pipe for drawing off the air and gases from the radiators with which said air-lines are connected.

Similar characters of reference are employed in all of the said above-described views to indicate corresponding parts.

Referring to the said Figs. 1 and 3 of the drawings, the reference character 1 indicates any suitable building, and 2 indicates any number of radiators or heaters suitably arranged upon the various floors of the building and which may be connected with any suitable source of supply by means of a supply-pipe (not shown) in the usual and wellknown manner. Each radiator is provided with an automatic air-valve 3 of any desired construction, and 4: indicates the airline or air-lines connected with the said valves, the said air-lines of the entire building terminating in a header 5 in the basement of the building and the said lines being graded so that any water entering the air-lines will flow by gravity to the said header in the basement. At the lowest point of the air-line or at such other point or points where it may be deemed advisable may be placed a suitable siphon 6 or other suitably-constructed trap to allow the water of condensation in the air line or lines to leave the air-line through a seal, so that any outside air cannot enter the air-line at the point where the drips or water are taken from it.

In the representation of the invention illustrated in said Figs. 1 and 3 of the drawings I make use of a tall flue, as 7, that is connected with or is in a building, as 8, adjacent to the building 1.

The rising-line or pipe 9 is carried up the inside of the chimney stack or flue7 to a point at or near the top thereof and is held in place by means of suitablehangers 10, either against one of the inner walls of the chimney or away from the inside wall, so that the hot gases may completely surround the said pipe 9 and thoroughly heat the same, as will be clearly evident. The lower. end of the said standpipe 9 is suitably anchored or secured so that the expansion will be up and down from a fixed point at the bottom, the hangers 10 being of sucha construction that the pipe can slip through the hangers without loosening them in the wall during the expansion and contraction of the stand-pipe. Suitably connected with the lower end of the stand-pipe 9 is a pipe 11, which communicates with the header 5, so as to establish a direct air-line from the radiators through the air-lines 4C, the header 5, the pipe 11, and the stand-pipe 9, as shown and for the purpose to be presently more particularly set forth.'

Where the stand-pipe leaves the stack or chimney it is fitted with a T or other plug, as 12, and directly beyond the same is a valve 13, as illustrated in said Fig. 1, so that should the stand-pipe 9 get dirty or have soot deposited on the inside through its opening at the top a steam-jet can be applied at the bottom of the stand-pipe by closing the valve 13 and removing the plug of the T, into which the steam is forced for eifectually blowing out the pipe.

In Fig. 2 of the drawings I have illustrated the application of my invention to an ordinary dwelling-house. In this view the reference character 14: indicates the ordinary chimney or flue into which the hot gases are discharged from the heater or boiler 15 in the cellar or from any other heater in any other part of the building. In this arrangement the air-lines 4 descend from all the radiators 2 into the basement or cellar and there are provide with the header 5 and siphon 6. A pipe 16 leads from the header 5 to a point within the flue or chimney 14, where it is connected with the lower end of the standpipe 17, extending to a point at or near the top of the said flue or chimney, the said pipe 17 being suitably secured in its position in the manner previously described.

From the above description of my invention and from an inspection of Figs. 1 and 2 of the drawings it will be clearly seen that I provide a system in which there are no movable parts, and the stand-pipe being arranged within a smoke stack or flue the pipe is heated, and thereby heats the column of air within the said pipe to approximately the temperature of the gases Within the stack or flue. The heating of the column of air in the said stand-pipe produces an upward draft, with a consequent suction on all the air-lines to which it is connected, thus assisting the circulation of the heating medium through the radiators or heaters and draws off the air or foul gases from the radiators or heaters and elfectually disposes of the same at the top of the stack or flue. The amount of suction on the air-lines will not be great, but will be in proportion to the height of the stack or flue and the temperature within the same, and such suction will be constant, as it is in no way affected by the opening and closing of by-passes or dampers in the stack or flue, and all disagreeablysmelling air or gases from the radiators will be discharged at the top of the chimney or smoke flue and there is no possibility of poisoning the atmosphere of the room.

The purpose of extending the pipes 9 and 17 to the top of the shafts 7 and 1 1 is that the entire line of piping may be heated by the hot gases in the shafts and that the smoke and gases in said shafts will not collect directly above the open ends of the pipes 9 and 17 so as to act as a retarding and dampening me dium upon the ends of the pipes, and thereby prevent any suction on said pipes, and consequently prevent the withdrawal of the foul gases from the radiators.

I am aware that it is a well-known and old custom to place a gas-jet in a flue leading to the top of a building; but such flues are of necessity supplied with outside air to keep the gases in proper state of combustion, and there is no stand-pipe rising to the highest point of the building in a hot or heated shaft. In those cases the successful Workings of the system are dependent upon such supply of outside air to keep the gas burning, for there are times in any steam plant when there will be no air whatever discharged from any radiator, and under those conditions there will be a stagnation of the air and the gas-jet would soon burn out the oxygen and small amount of air surrounding it and go out. This is all avoided by placing the stand-pipe connected with the air line or lines directly Within a hot shgft or heated shaft, as indicated in Figs. 1 an 2.

IIO

Iam aware that changes may be made in the various arrangements and combinations of the device and their parts Without departing from the scope of my present invention. Hence I do not limit my invention to the exact arrangements and combinations of the devices and their parts as described in the previous specification and as illustrated in the accompanying drawings, nor do I confine myself to the exact details of the construction'of any of the said parts.

Having thus described my invention, what I claim is-- 1. The combination, with a heating system, comprising, a radiator and an air-line, of a hot or heated shaft, a stand-pipe in said shaft, said stand-pipe entering said shaft at a point near its bottom and terminating at a point near its top but below the upper open edge of said shaft, and said stand-pipe being heated by said shaft, said stand-pipe being also connected at a low point with said air-line forconducting the foul air from the radiator and said air-line to the highest point of said shaft, substanterminate, a hot or heated shaft, a stand-pipe in said shaft, said stand-pipe entering said shaft at a point near its bottom and terminating at a point near its top but below the upper open edge of said shaft, and said stand-pipe being heated by said shaft, said stand-pipe being also connected at a low point with said airlines for conducting the foul air from the radiators and said air-lines to the highest point of said shaft, substantially as and for the purposes set forth.

3. The combination, with a heating system, comprising, radiators, air valves, and airlines, of a header in which all of the air-lines terminate at their lowest points, a trap or water seal in said air-lines, a hot or heated shaft, a stand-pipe in said shaft, said standpipe entering said shaft at a point near its bottom and terminating at a point near its near its top but below the upper open edge of said shaft, and said stand-pipe being heated by. said shaft, said stand-pipe being also connected at a, low point with said air-line for conductingthe foul air from the radiator and said air-line to the highest point of said shaft, 5

and an expansion means in said shaft for attaching said stand-pipe in position within said shaft but allowing for the expansion of said pipe when heated, substantially as and for the purposes set forth.
